Chapter 1 Introduction

1.1 Introduction

DDS-3005 USB Arbitrary Waveform Generator has one channel of arbitrary
waveform output, 8 Bits output, synchronized signal outputs, two channels of
Counter/Frequency Measurement inputs, 8 Bits input and external trigger input.
User can edit the waveform arbitrarily by the mouse or choose the regular
waveforms such as Sine, Square, Tri-angle, Saw-tooth, TTL, White Noise,
Gauss Noise, Trapezia, Exponent, AM and FM. The parameters, such as
amplitude, frequency and offset, are also settable. The data format of
DDS-3005 USB is completely compatible with that of Tektronix; it can directly
read the waveform data files produced by the Tektronix oscilloscope or
Tektronix waveform editor software and redisplay the waveform. DDS-3005
USB adopts the DDS technology so that it has the advantages of high
frequency accuracy, high waveform resolution, high reliability, and wide
software support. It can be widely used in the various kinds of electronics labs
and it offers complete interface for second time development to be jointlessly
inserted into other auto-measuring systems.

1.2 Working Principle

The PC transfer the waveform data to the memorizer of the signal generator
via the USB bus, the ID counter cycles and send the period waveform data to
the DAC circuits, the DDS (Direct Digital Synthesized) circuit produces the
corresponding DAC refreshing clock. The waveform of DAC is outputted
through the Cache magnifier, Low Pass Filter, and the Magnifier. The
frequency counter can test the external frequency.
